Elastomers: Chloroprene, CPE, Glycine

Showa Denko Chloroprene (CR) is a synthetic rubber which is manufactured via polymerization of chloroprene monomer. It is characterized by a well-balanced profile of properties:

• exceptional resistance to weather, sun, ozone, and abrasion
• good resilience
• gas impermeable
• resistant to heat, oil and flames
• functions well at low temperatures
• good electrical properties

Showa Denko Chloroprene is available in solid form as well as liquid dispersion. Showa Denko Europe GmbH offers a great variety of different grades to customers in Europe.

Typical applications for liquid dispersions

• water based adhesives
• dipped goods, such as gloves or balloons
• waterproof coatings for the construction industry

Typical applications for solid grades

• solvent borne adhesives
• anti-vibration engine mounts
• wire and cable, gaskets, boots, seals
• moulded and extruded goods
• foamed sheets for wet suits or laptop covers
• bearing pads for bridge or road construction
• belts and hoses for automotive and general industry

Showa Denko started the production of Chloroprene Rubber at the Kawasaki plant, approximately 20km south of Tokyo, in 1963. Since then, we developed a great variety of grades which meet our customers’ requirements.

In 2002, Showa Denko started selling the Showa Denko Chloroprene to export markets, to Europe since 2004. Today, we have acquired high reputation with our customers due to excellent product quality and a well established network of distribution and logistics partners.

With our warehouse in Hamburg, we ensure improved product availability and short lead times for our customers in Europe.

Elaslen™ is Showa Denko’s trade name for Chlorinated Polyethylene (CPE). It is a thermoplastic polymer, manufactured by chlorinating high density Polyethylene (HDPE).

Elaslen™ is produced at our plant in Kawasaki, Japan, since 1968.

Elaslen™ shows excellent flexibility even at low temperatures, weatherability, heat aging resistance, flame retardancy, color stability, compression set resistance, electrical insulation properties (volume resistivity up to 4 x 10¹⁶ [Ω·cm]), as well as oil and chemical resistance.

Elaslen™ is offered in powder form.

For detailed information, please download our Grade List here.

Due to its characteristics, Elaslen™ is suitable for a variety of applications, such as:

• Wire & cable jackets
• Automotive and industrial tubes and hoses
• Gaskets, seals, bellows
• Hand-rails
• Roller covers
• Magnetic rubber
• Flame retardant for ABS (FR-ABS)
• Impact modifier for PVC

The properties of CPE are mainly determined by 3 factors:

• Chlorine content
• Molecular weight
• Crystallinity

The different grades in our Elaslen™ product range are differentiated by the combination of these 3 factors. They have influence on the flame retardancy, mechanical strength, chemical resistance, and heat aging resistance.

By these factors and their effects, the best suitable grade of Elaslen™ can be identified for each application.

Glycine, also known as amino acetic acid, is an organic compound with the chemical formula NH₂CH₂COOH.

It is produced by Showa Denko in Kawasaki, Japan, since 1974.

Glycine is supplied as sweet tasting, odorless, white crystalline powder (state of solution: transparent and colorless).

• Pet food additive
• pH buffer (adhesives, cosmetics)
• infusion solutions
• Chelating agent
• CMP slurry (chemical-mechanical planarization)
